老人清晨四步曲研究显示,心脑血管疾病多在深夜和凌晨发作,而心肌梗死、心源性猝死和中风的发病率以清晨为高。凌晨4点左右,人的心跳与呼吸速度减慢,生命活动处于最低点,此时心脑动脉的血流极缓,易致血栓形成,心脑缺血;而清晨当人从“半休眠”状态苏醒时,呼吸心跳加快,血流加速,血压升高,又易使已老化的心脑血管破裂。为防不测,脑动脉硬化、高血压、心脏病患者以及年老体 Early morning four-step song study shows that cardiovascular disease mostly in the late night and early morning attack, and myocardial infarction, sudden cardiac death and stroke incidence in the early morning high. About 4 am, people’s heart rate and breathing rate slowed down, life activities at the lowest point, this time the flow of cerebral artery very slow, easy to cause thrombosis, cerebral ischemia; and early morning when people from the "When the state is awake, rapid breathing, rapid blood flow, blood pressure, and easy to make the aging of cardiovascular and cerebrovascular rupture. To prevent the accident, cerebral arteriosclerosis, hypertension, heart disease and the elderly
